IMPROVEMENT IN CANE-SHAVING MACHINES.

Specification forming part of Letters Patent No. 2 16,723, dated J unc 24, 1879; application filed March 24, 1879.

To all whom it may coitcem:

Be it known that I, GEORGE S. OoLBURN, of Gardner, in the county of Worcester and Commonwealth of Massachusetts, have inventedan Improvement in Cane-Shaving Ma chines, of which the following is a specifica- This invention consists in providing a machine for shaving rattan and other cane with means whereby the feedway, trimming and gaging disks, pressure rolls, and shavingknives are given a variety of adjustments in relation to the feed-roll for increasing its capacity and utility.

In the drawings, Figure 1 represents an end elevation of my machine; Fig. 2, an elevation onthe opposite side, showing the method ofobtaining the adjustments named. Fig. 3 is a plan. Fig. 4 illustrates the method of adjustin g the ed ge-trim1nin g disks. Fig. 5 shows the method by which the pressure-roll is supported and adjusted. Fig. 6 isa detail view, further illustrating the construction of the device shown in Fig. 5. Fig. 7 is a View, partin elevation and part in section, to illustrate the construction and operation of the machine. Fig. 8 shows a piece of rattan-cane with its edges partly shaved by the edge-trimming devices and the strand partially shaved therefrom by; the action of the shaving-knives.

The feed-roll A is provided with the circumferential groove to. It is made of steel and is secured to the driving-shaft A in such amanner as to be removable, as it is necessary to take it off from time to time to renew the groove.

The disks B are each supported by a post, I), having horizontal adjustment in relation tothe feed-roll upon the arm 0, projecting from the hood-piece O, by means of the set-screws b b and slots b The hood-piece or bracket 0 carries a table, I), which supports the mouth-piece d, and is fastened to the frame E by the set-screw c and, by means of said set-screw and slot 0 and screw 0 the said bracket, together with the mouth-piece and cutting-disks, is vertically adjustable in relation to the feeding'roll.

The feedway to the rolls is provided with thefflaring mouth-piece d and the rolls d having their axes at right angle to the line of feed, each of which is supported at the end of an arm, d pivoted at (Z to the table D. These arms are fastened together by the spring at, and their opposing faces form the continuation of the feedway from the end of the mouthpiece to the point of contact of the pressure and feeding rolls.

The pressure-roll F is fastened at the end of its operating-shaft), and it is provided with a vertically-yielding adjustment in relation to the circumference of the feed-roll byineans of the box f upon the end of the yielding rod f which is supported by the clamping-nutf on the bracket Gr.

The spring f surrounds the rod, and be tween the bearing f and f bears against the pin f and gives the requisite stress or tension to the pressure-roll.

The box furnishing the bearing of the press ure-roll shaft is made, preferably, as shown in Fig. 6, of the hanger m, which is fastened to the block 50 and the piece .70 which forms the upper half of the box and is made adjustable in relation to the block as by means of the setscrews 0: This construction provides for the necessary adjustment of the box to the changes occasioned by wear. As the bearing portion of the piece 00 becomes worn it is moved downwardly.

The bracket Gr carries the shaving-knives H, arranged to project across the feed-roll, one beyond the other.

In front of each oftheseknives isasmall pressureroll, h, arranged to bear upon the feed-roll, and provided with yielding vertical adjustment in relation to the feed-roll in the same manner and by like means as described in connection with the pressure-roll F. They are fastened at the end of their respective shafts h, and are provided with bearings in boxes supported by the bracket G in the same manner as the box as. The bracket Gr, carrying the pressurerolls and shaving-knives, is provided with vertical adjustment upon the frame E, by means of the set screw g and slot g, and the portion g is arranged to fit within a recess of corresponding shape in the frame E to properly secure the bracket to the frame. Between the upper one of these pressurerolls h. and the cuttingdisks, and fastened to the posts I), are the spring-guides M. They project above the circumference of the feed-roll, one upon each side, and serve to hold the strand in the groove while it is passing from the first pressure-roll to the second.

The shafts f and h are operated in any suitable manner, but preferably by rolls upon the end of each, arranged to contact with the periphery of wheel N on shaft A and to be revolved thereby.

The check-nutf for adjusting the rod supporting the pressure-roll shafts, is provided with the short locking-screw 0, which is loosened when adjustment is made, and is tightened against the end of the screw upon the said rod in locking the same.

The cutting-disks B are provided with means for revolution, whereby, as the portion of the cutting-edge in use becomes dull, a new edge maybe presented. This adjustment is effected by supporting each disk B upon a gear-wheel, B, which is provided with a suitable bearing on the stud b, projecting from the post I). This gear-wheel is provided with. the bevel-gear b upon its inner surface, and which is arranged to mesh with the bevel-gear b on the lower end of the shaft 1)". To enable this to be accomplished the post I) is provided with a circular recess, b into which the said bevel-gear projects.

The disk may be fastened upon the gearwheel by keying or by a nut, or by ahead upon the stud, or in any other suitable manner.

- The shaft has suitable bearing in the post, and is fastened therein by means of the collar 1)", which surrounds the same just above the bevel-gear b and also forms a support therefor, as the shaft is somewhat reduced in size at that point, and the collar fits over the reduced portion, allowing the shoulder b to bear upon the upper edge of the collar. Thepressure-rolls may be corrugated or roughened.

In operation the trimmin g-disks are adjusted horizontally in relation to the edge of the feedroll to the gage which it is intended that the strand to be shaved shall have. The shavingknives are adjusted vertically in relation to the roll to secure the gage for the thickness of the strand. The piece is then introducedthrough the mouth-piece between the vertical guiding-rolls, with the strand-forming part lowermost, and is laid hold of by the feed and pressure rolls, which advance it to the action of the shaving-knives, which remove a narrow, thin strip from each edge of the piece. This determines the width of the strand. The strand, advancing by the continued action of the pressure and feed rolls, is passed between the vertical guides attached to the cutting-disk posts, is laid hold of by the second pressureroll in the train presented to the first knife, which partially reduces its thickness, and then to the second pressure-roll and knife, which removes a second strip, and reduces it to the desired thickness.

It will be observed that the guiding-rolls have automatic adjustment for varying widths of strands; that the said guiding-rolls, mouthpiece, and cutting-disks and pressure-rolls are vertically adjustable in relation to the circumference of the feed-roll; that the cutting-disksare provided with horizontal adjustment not only for the purpose of gaging the width of thestrand,butalso to enablethe disks to be moved as they wear away from frequent sharpening; and that the shaving-knives and their pressure-rolls are adjustable vertically in relation to the feed-wheel. By thus making the parts adjustable to the feed-wheel in the manner set forth, not only are varying widths and thicknesses of strands shavedin the same machine, but, as the feed-roll wears, the devices named are readily adjusted to -the new position produced by shortening the diameter of the roll without changing their relative positions.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a machine for shaving rattan or other cane, the combination of a revolving feed roll or bed, a revolving pressure-roll arranged to co-operate with said feed-roll in feeding the cane, with the gagedisks B, supported upon the posts I), the hood-piece O, and means for vertically adjusting the same, substantially as and for the purposes described.
